HiI have recently installed orange. After opening the Canvas, I see only data table widget highlighted. As a result I am not able to do any computation. Initially, two widgets were also available in visualize but now they also appear gray.

I have uninstalled orange and all associated packages and then re-installed it. But the problem remains. Please help me in this regard. I have tried to search the option to load widgets but failed to locate.

The content of the output window displayed below

There were problems importing the following widgets: OWC45Tree: c45 is not found OWItemsetViz: No module named OWNetworkCanvas OWRScript: No module named rpy2.robjects OWLinProj3D: No module named OpenGL OWNxExplorer3D: No module named OWNxExplorerQt OWScatterPlot3D: No module named OpenGL OWSphereviz3D: No module named OpenGLThe following widgets could not be imported and will not be available: OWSphereviz3D, OWScatterPlot3D, OWLinProj3D, OWC45Tree, OWNxExplorer3D.The following prototype widgets could not be imported and will not be available: OWRScript, OWItemsetViz.

Have you tried clicking the widget buttons?Most of the widgets recently got new icons, which follow a more black and white style. This somewhat clashes with the default background they get.

i have the most recent version installed, and at some point i did have the new icons.

now most of the icons are missing, and i haven't changed anything in the installation at all. only thing i've really done of consequence has been to reboot my pc since the last time the icons were displayed correctly.

Thanks a lot Ales for responding to my query. As I am new, I'll try one by one all the suggestions that has appeared here.

However, in my case the icons of widget appear (in Gray) and I can put them on canvas. The problem is that I do not get any output. Only a blank output screen appears. Further, when I attach the data file to any widget an yellow triangle with question mark appear. But when I attach the file with data table widget (which is functional) and then I attach the data table to any widget the said problem goes away. But even in this case also the other widgets do not function (as indicated by blank output file). Alels, I again thank you for all. I'll revert back with whatever result I get.

Further, the output file does not appear in the image linked in my earlier post. The content of the output file is pasted below

Thanks a lot for all your help. I tried the 'visualize' icons with the data file and all of them are working. However, I am not able to perform ROC or other multivariate analysis. Hope, there must be some problem in organizing my data. Though, I used the select attribute and other required modules, I think that I am not giving the data to Orange in required format. I'll try to learn about them from the information available on web page.
